Determining the number of files in a directory
This is probably a dumb question; however, I never let a little thing like that bother me in the past. Using FreeBSD-6.2 and Bash, how do I determine the number of files in a given directory? I have tried all sorts of combinations using different flags with the 'ls' command; however, none of them displays the number of files in the directory. Other than, by writing a script to accomplish this feat, how could I achieve my goal? Thanks! -- White Hat [EMAIL PROTECTED] __ Do You Yahoo!? Tired of spam? Yahoo!

Using FreeBSD-6.2 and Bash, how do I determine the number of
files in a given directory? I have tried all sorts of
combinations using different flags with the 'ls' command;
however, none of them displays the number of files in the
directory.
$ ls | wc -l
will show you how many files and directories in the current
(target) directory. To count just files, and exclude directories,
you could try something like
$ find /target/directory -type f -print | wc -l
Except of course, that would descend into the subdirectories you're
trying not to count... Sorry - an object lesson in not hitting send
before you've tested what you scribbled.
find /target/directory -type f -maxdepth 1 | wc -l
should do the trick. See also man find and man wc, of course.
That's better than ls(1), which is terribly slow at displaying
(actually: at sorting) large directories. In this case, better
turn off sorting with 'ls -f':
$ time ls -f /usr/local/news/News | wc -l
0.42 real 0.29 user 0.07 sys
35935
$ time ls /usr/local/news/News | wc -l
147.02 real33.92 user 0.07 sys
35935
And ls -lf makes working with awk faster, too. E.g:
% ls -lf | awk '$8 == 2007 {print $9}'
% ls -ltf | awk '$8 == 2007 {print $9}'
If you've got a large number of files, ls -lf is roughly
twice as fast.

I find that the most intuitive way is to use something like: find . -maxdepth 1 | wc -l Where you can specify how many levels of subdirectories to include in the count. Please note that count also includes the current directory (.). To exclude hidden files (.*), use find * -maxdepth 0 | wc -l or expr `ls -l | wc -l` - 1 instead.
